Veerle Cnudde, Exploring the Potential of X-ray Tomography as a New Non-destructive Research Tool in Conservation Studies of Natural Building Stones, Ghent, Ghent University, 2005.

Resumo:

The mean purpose of this study was primarily the exploration of the possibilities of the non-destructive X-ray micro-CT technique in the domain of conservation and restoration of natural building stones. Special attention was paid to more specific topics like visualization of conservation products inside natural building stones, determination of porosity and pore-size distribution of scanned samples and monitoring of artificial weathering processes. Additionally the influence of conservation products on the original properties of stone material was also studied. High-speed neutron tomography was introduced as a new non-destructive visualisation technique and tested for its potential in fluid-flow research inside building materials.
